From 421777a02bbd9cdabe0ae05a69ee06253150589d Mon Sep 17 00:00:00 2001 From: =?utf8?q?Barnab=C3=A1s=20Cz=C3=A9m=C3=A1n?= Date: Mon, 21 Apr 2025 04:04:17 +0200 Subject: [PATCH] soc: qcom: smp2p: Fix fallback to qcom,ipc parse MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit mbox_request_channel() returning value was changed in case of error. It uses returning value of of_parse_phandle_with_args(). It is returning with -ENOENT instead of -ENODEV when no mboxes property exists.
